A senior citizen, eyeing a parking spot that had just been vacated at a mall, was slowly backing up his aging luxury car, to get room to maneuver into the spot when a teenager in a small, red sportscar came from the other direction and zipped into the spot.  Jumping over the side of his little car, the youth called out, "That's 'cause I'm young and fast."  The old man revved up his engine and plowed ahead—straight into the little sportscar folding it up like an accordion.  Then, turning to the horror-stricken youth, he said, "That's 'cause I'm old and rich."
